Abstract: A method for producing a ceramic matrix composite part, includes forming a fiber preform from a plurality of fibrous structures including core-shell particles, the core-shell particles including a core portion formed by a core of ceramic material and a shell formed by an adhesive layer, the adhesive defining an outer surface of the core-shell particles and completely coating the core of ceramic material, and sintering the core-shell particles in the fiber preform obtained in order to form the ceramic matrix in the porosity thereof.

Abstract: A method for manufacturing a part made of composite material, includes the arrangement of a fibrous preform in the impregnation chamber of a mold, the impregnation chamber being closed by a flexible membrane separating the impregnation chamber from a compaction chamber, an impregnation fluid being injected into the impregnation chamber and a compression fluid being injected into the compaction chamber, the compression fluid being a liquid in which the value of the density is between 60% and 125% of the density of the impregnation fluid.

Abstract: A support tooling for porous preforms intended to be infiltrated by a molten metal includes a rack including two suspension bars each extending longitudinally along a first direction, the suspension bars being held spaced apart from one another along a second direction perpendicular to the first direction; a plurality or porous preform supports removably mounted on the suspension bars, each support including a first portion connected to one of the suspension bars by a connection sliding along a third direction perpendicular to the first and second directions and a second portion extending from the first portion and including support elements which are able to hold a porous preform by point or linear contact.
